In 5.10 the convert gained support for extended inode time precision, but this is not available on older distros and breaks build. Add a configure-time check for the EXT4_EPOCH_MASK macro and add a stub in case it's not detected. This means that the 64bit timestamps will not be transferred from the original filesystem in such environment, at least a warning is printed.
